Title:  

"Recent Observations of the MBR at the Owens Valley Radio
Observatory; and the Status of the Cosmic Background Imager under
construction at Caltech"

Abstract:

Observations of the CMBR at the OVRO at 14.5 GHz and 32 GHz have revealed
the presence of a previously unsuspected component of galactic foreground
emission.  The dual frequency measurements are used to subtract off this
foreground, and hence an accurate measurement of the intrinsic anisotropy
 on angular scales 7'-22' is determined. This result, together with
previous OVRO observations will be compared with standard models. 

The Cosmic Background Imager (CBI), now nearing completion at Caltech, is
a 13-element 10-channel interferometer, designed for high sensitivity
observations of the CMBR. The design, status and capabilities of this
instrument will be presented.
